Python:  A bit shift is a procedure whereby the bits in a bit string are moved to the left or to the right. For example, we can shift the bits in the string 1011 two places to the left to produce the string 1110. Note that the leftmost two bits are wrapped around to the right side of the string in this operation. Define two scripts, shiftLeft.py and shiftRight.py, that expect a bit string as an input. The script shiftLeft shifts the bits in its input one place to the left, wrapping the leftmost bit to the rightmost position. The script shiftRight performs the inverse operation. Each script prints the resulting string.

Question
Python: 

A bit shift is a procedure whereby the bits in a bit string are moved to the left or to the right.

For example, we can shift the bits in the string 1011 two places to the left to produce the string 1110. Note that the leftmost two bits are wrapped around to the right side of the string in this operation.

Define two scripts, shiftLeft.py and shiftRight.py, that expect a bit string as an input.

  • The script shiftLeft shifts the bits in its input one place to the left, wrapping the leftmost bit to the rightmost position.
  • The script shiftRight performs the inverse operation.
  • Each script prints the resulting string.

 

**Example of shiftLeft.py Input and Output:**

- **Input:** Enter a string of bits: Hello world!
- **Output:** ello world!H

This demonstrates a left shift operation on the string "Hello world!", moving the first character to the end.

---

**Example of shiftRight.py Input and Output:**

- **Input:** Enter a string of bits: Hello world!
- **Output:** !Hello world

This illustrates a right shift operation on the string "Hello world!", moving the last character to the front.
